.SH NAME
vfdecrypt \- decrypt encrypted filevault disk images
.SH SYNOPSIS
.B vfdecrypt
-i in-file [-p password | -k aeskey [-m hmacsha1key]] -o out-file
.SH DESCRIPTION
vilefault decrypts encrypted Mac OS X disk image files. It supports both version 1 and 2 of the non-documented proprietary format. It is possible to pass either a password or a concatenation of an aeskey and the HMAC SHA-1 key. If a password is passed, the aeskey and the hmac will be derived. If an AES key is passed, you should either pass an SHA1-HMAC directly after the aes key or after '-m' directly.
